[Successful Application of Cathode Casting Technology in Phase II Electrolytic Aluminum Project of Zhalantun Aluminum] Recently, there has been significant good news from the Phase II project of Zhalantun Aluminum undertaken by SPIC, which was contracted by Shenyang Engineering & Research Institute: the first batch of cathode carbon block groups with phosphorus cast iron successfully cast and passed acceptance, marking the official entry of the project into the comprehensive construction phase. As the core technology of the project, the cathode casting technology was independently developed by Shenyang Engineering & Research Institute in 2016 and is hailed as a "game-changer" technology. This technology can significantly improve the current efficiency and operational stability of electrolytic cells, achieving energy savings of 200-500 kWh per ton of aluminum. It has been successfully selected into the "China's Energy-Saving Technology Path for Electrolytic Aluminum" and has won multiple honors, including the first prize of the Science and Technology Progress Award from the China Nonferrous Metals Industry Association. This technology has now been successfully applied in over 40 electrolytic series with capacities ranging from 200 to 600 kA, covering a production capacity of 13 million mt/year. It is expected to save over 3 billion kWh of electricity per year and reduce carbon dioxide emissions by nearly 2 million mt/year.
